I just finished my 100 last night, with Ravenholdt and 10 hours of LBRS pickpocketing.
(Voidlich-Whisperwind in case you check my rep for Ravenholdt, Did the Goblin Reps and Ravenholdt on him for the Insane Achivement which I will have come time next DMF).
Last I checked I believe I am 84/90 I really want the 100 Rep Mount but I also have so many other things to grind that unless a mount is tied to a faction it gets put on the backburner.
I think I have less like 6 exalted reps total. 4 ARs, August Celestials from MoP, and Gilneas on my worgen for the heritage. Other than that I mostly avoid rep when I can, ARs were pretty much the one thing that could make me go through with it. I think I did the mop one for a bag recipe that was sweet, but I almost unsubbed doing those dailies.
Got it a couple of months ago. Only have two more left. Warsong shouldnt much longer. At 500 a week, Ill finish Black Prince in 45 weeks assuming I don’t miss a week.
